摘要
针对地球模拟器(ES)的结构，开发并优化了光谱大气环流模式AFES (AGCM for Earth Simulator)。ES是一种大规模并行矢量超级计算机，由640个处理器节点组成，通过单级横杆网络相互连接，利用ES的全部640个节点配置，利用AFES进行高分辨率模拟(T1279L96)，其总峰值性能达到40.96 Tflops。由此产生的计算效率是峰值性能的64.9%，远远超过了传统的天气/气候应用程序，即使在矢量并行计算机上也只有25-50%的效率。这一显著的性能证明了ES在实际应用中的有效性。
A 26.58 Tflops Global Atmospheric Simulation with the Spectral Transform Method on the Earth Simulator
A spectral atmospheric general circulation model called AFES (AGCM for Earth Simulator) was developed and optimized for the architecture of the Earth Simulator (ES). The ES is a massively parallel vector supercomputer that consists of 640 processor nodes interconnected by a single stage crossbar network with its total peak performance of 40.96 Tflops was achieved for a high resolution simulation (T1279L96) with AFES by utilizing the full 640-node configuration of the ES. The resulting computing efficiency is 64.9% of the peak performance, well surpassing that of conventional weather/climate applications having just 25-50% efficiency even on vector parallel computers. This remarkable performance proves the effectiveness of the ES as a viable means for practical applications.
